The apparatus includes an electrically operated clock |2 which has as apart the 'eof a time setting mechanism It and a spring controlleddelower terminus of the driving geari25, a hub diameters to provide,ashoulder.

pressor member l4 formed of an upper pivotally supported part I5, acurved part l6 which merges at its upper end into the lower end of thepart l5 and a lower part H. which merges at its upper end into the lowerend of the part I6. The part I1 is formed with an angularly disposednose I 8. The part I 5 is suspended from its pivot IS.

The mechanism I3 is of normal construction,

such as the alarm setting mechanism of an alarm 10 clock with thisexception, that a cam .20 constitutes a part thereof. The mechanism |3includes an axially apertured transparent disc 2| having its outer facein the'form of a clock dial,

a setting gear 22 spaced from and opposing the inner face of disc 2|, arotatable shaft 23, a controlling spring 24 encompassing shaft 22, a 26,a rabbeted collar 21, a sto-p'collar 28 and a nut 29. The disc 2| ismounted in the rabbet of and extends outwardly from and is retained oncollar 21 by the collar 28. The collars 21 and 28 are mounted on shaft23. The collar 21 is anchored to the shaft 23 by a pin 30. A nut 29threadedly engages with one 'end of shaft 23 retains collar 28 on thelatter. A hub 26 is integral at one end with and extends inwardly fromthe gear 22. The hub 26 is mounted on shaft 23 and has the cam integralwith the other end thereof. The gear 25 is carried by that end of shaft23 opposite collar 3| is mounted on shaft 23. The spring- 24 isinterposed between the cam 20 and the collar 3| and frictionally clampsgear 22 to collar 21. Under normal conditions the spring 24 provides forthe bodily rotating of the gear 22 with the shaft 23. The hub 26 is oftwo outer That portion of reduced outer diameter of the hub 26 ismounted in a support 32. Thelijhaft 23 extends rearwardly from hub 26and t ough a support 33. They peripheral shoulder on hub 26 abutssupport 32. The cam 20 has a high edge part 34, a lower edge part 35 ofless length than the edge part 34 and a shoulder 36 at-which' the lowerend of edge part'35 terminates. The other end of edge part 35 mergesinto edge part 34. e

The edge part 35 and shoulder '36 provide a notch. The gear 25 isoperated from a train of gearing 31 The gear 22 has its outer faceprovided with a pointer 39 w ch is visible through disc 2|. A toothedstem 40 is provided for setting gear 22 relative to disc 2|.

The frame structure supporting the clock train 55 30 the end on whichis'mounted the nut 29. A

driven from the clock train 381 upstanding portion shifting element 48is the element 48 whereby 38 is indicated at 4|. The structure 4| at itsbottom includes a pair of rearwardly extending spaced arms 42, 43. Thelatter is arranged at higher elevation than the former. Arranged belowthe arms 42, 43 is a resilient member 44 and positioned on the latter isa plate 45 and a plate 48 spaced from plate 45. The resilient member 44and plate 45 are secured to the arm 42 by the holdfast means 41. Themember 44 is secured to the lower is. cc of the plate 45 and the latteris arranged in spaced relation with respect to the arm 42. Secured tothe lower face of member 44 and extending from one end thereof is anangle-shaped shifting element 48 for a purpose to be referred to. Theelement 48 includes an 49 terminating in a right angularly disposedupper terminal portion 58. Interposed between the plate 46 and themember 43 as well as secured to the upper face of the plate 45 is ametallic strap 5| formed to provide an inclined abutment 52. The nose I8of the depressor member M is for engagement with the abutment 52 for thepurpose of depressing member 44 carrying the shifting element 48therewith to the position shown in Figure 6 and for holding it in suchposition for a pre-determined period until the time setting mechanism isoperated to an extent to provide for the cam 28 coacting on member l4 toshift it to the position shown in Figure 7. When member 44 is shifted tothe position shown in Figure 7, the released and it will be caused tomove upwardlydue to the action of the member 44. The arm 42 constitutesa stop for limiting the upward movement of the member 44 and element 48.

There is associated with the member l4 an upstanding controlling spring53 having its lower portion anchored at 54 with the structure 4|. Themember l4 has its pivoted end arranged above shaft 23 rearwardly withrespect to the gear 22. The member I4 is substituted for the alarmactuating mechanism of an alarm clock. The lower end of part |5 ofmember I4 is pro--.

. vided with a depending offset angle-shaped holding member'55'whichcoacts with the high edge part 34 for maintaining the member l4 inposition to depress member 44 against the action of controlling spring53 which bears against the part |5 of member l4 during the rotating ofthe cam. The holding member 55 during the rotation of the cam willeventually engage the notch in the cam whereby pressure of the spring 53will move part l5 of member l4 and the latter will assume the positionshown in Figure '1 to release the element 48 whereby element 48 will beele-' vated due to the action of member 44. The holding member 55 willbe retained in notch in cam 28 for a pre-determined period that is tosayuntil the time setting m chanism is actuated to such an extent as toprovide for the cam rotating to cause member 55 to ride on the high edgepart of cam 28 thereby causing member H to depress member 44 and lowerelement 48.

Supported from the structure 4| is a hanger 56 for a knife switch 51including a pair of bifurcated'posts 58, 59. The blade of switch 51 isindicated at 58 and pivoted at one end, as at 5| to the post 59. Theblade 68 has an opening 82 and extending through the latter is the end58 of blade 68 and element 48 are connected together. On the upwardmovement of the element 48, the blade 60 is shifted from the dotted lineposition shown in Figure 8 to the full line position thereby closing thecir-- to full line position automatically closed automatically, by amotor 89 of the clock are cuit which will be referred to. On thedownward movement of element 48 the blade is shifted from full lineposition to dotted line position. The blade 60 is shifted from dottedline position by the time setting mechanism.

The blade 58 is shifted from full line position to dotted line positionautomatically from the time setting mechanism.

The blade 68 is shifted from full line position to dotted line position,that is to say to open the switch when the latter is not to be openedand manually operated element 63 consisting of a forked member 84pivoted upon the structure 48 and provided on one of its tines 65 withan extension which projects outwardly from the back of theclock. Thetine 55 has connected thereto a bar 61 disposed at right angles to theextension 66 and positioned above one end of the blade 50. When theextension 86 is shifted downwardly, the bar 61 is carried therewith andengages blade 50 to move the latter from circuit closing position tocircuit opening position and to retain it on such position as long asdesired.

The clock |2 includes a housing formed of two sections detachablyconnected together. The sections are indicated at 68, 59. The former isthe front section and the latter the rear or back section. The section58 carries the structure 4|. Section 89 has connected with the topthereof a manually operated circuit opening and closing switch indicatedat 18. The switch 10 extends outwardly of and depends from the top ofsection 18. r

The apparatus when associated with a radio receiver may include anautomatically closed and automatically opened controlling circuit and amanually closed and manually opened controlling circuit for the-powercircuit of the said receiver and such circuits are shown. The saidautomatically closed and automatically openedcontrolling circuit for thepower circuit of the radio receiver includes the conductors 1|, 12, 13and 14. The said manually closed and opened controlling circuit includesthe conductors 13 and 14. The conductors 1|, 12 extend from switch 51 tothe switch 10. The conductors 13, 14 extend from switch 10 to a socket15 which is attached to the section 69 of the housing. The conductors13, 14 pass through an opening 16 and are connected to socket 15. Theswitches 51 and 18 are in parallel.

Extending from the posts 11, 18 of socket 15 are circuit conductors 19,88 respectively connected to a plug 8| for engaging in a socket 82attached to a power line not shown. The conductors 19, 88 are enclosedina casing 83. The socket 15 includes another post 84, a pair of contacts85, 86, a conductor 81 between post 11 and contact 85 anda conductor 88between post 84 and contact 88. The circuit conductor 14 is connected topost 84. The conductor 13 is connected to post 18. Leading from theposts 11, 18 to the the circuit conductors 98, 9| respectively. Theradio receiver 92 is shown as indicating a power circuit forming meansarranged within a cable 93. The latter includes a plug 94 for extensioninto the socket 15 to electrically engage the contacts 85, 88. The powercircuit is connected in a known manner to receiver 92.' The apparatuswhen used in connection with a radio receiver is to volume control whichassociates with the volume control of the receiver 92 and these controlsare be provided with a,

indicated at 95, 95. The control 95 is arranged.

in the apparatus and the control 96 in the receiver. Circuit connectionsbetween the controls 95, 95 are indicated at 91 and extend through thecable 93. Control 96 is interposed in the circuit 91 which leads fromthe control 95. The arrangement is such that the volume may becontrolled from the clock or the radio receiver.

When the switch 61 is automatically closed due to the action of the timesetting mechanism with respect to the depressor member H, thecontrolling circuit consisting of the conductors ll, 12, 13, 14 will beclosed thereby providing for the operation of the radio receiver. Whenthe switch I is manually closed, the controlling circuit provided by theconductors 13, 14 will be closed and the receiver made active.

The time setting arrangement which is connected to the member I4,element 48 and switch 51 provides means, when the apparatus is inset inconnection with a radio receiver whereby a selected broadcasting stationwill be automatically cut in at a pre-determined time for apredetermined period and automatically cut out at the end of suchperiod.

The time setting mechanism corresponds in structure to and operates inthe same manner as the well-known alarm setting and alarm actuatingmechanism of clocks, with this exception that the cam 20 and holdingmember 55 are substituted for the alarm and alarm actuating means.
